High-performance electromagnetic interference (EMI) shielding materials with ultraflexibility, outstanding mechanical properties, and superior EMI performances are highly desirable for modern integrated electronic telecommunication systems in areas such as aerospace, military, artificial intelligence, smart wearable electronics. Herein, ultraflexible mechanically strong aramid nanofiber–Ti3C2Tx MXene/silver nanowire (ANF-MXene/AgNW) nanocomposite papers double-layered structures fabricated via the facile two-step vacuum-assisted filtration followed by hot-pressing approach. The resultant a low MXene/AgNW content of 20 wt % exhibit an excellent electrical conductivity 922.0 S·cm–1, properties tensile strength 235.9 MPa fracture strain 24.8%, effectiveness (EMI SE) 48.1 dB, high SE/t 10 688.9 dB·cm–1, benefiting from efficient structures, high-performance ANF substrate, extensive hydrogen-bonding interactions. Particularly, show maximum 3725.6 S·cm–1 SE ∼80 dB at 80 absorption-dominant mechanism owing to massive ohmic losses conductive layer, multiple internal reflections between Ti3C2Tx MXene nanosheets polarization relaxation localized defects, abundant terminal groups. Compared homogeneously blended ones, possess greater advantages electrical, mechanical, performances. Moreover, multifunctional thermal management Joule heating temperature supplied voltages, rapid response time, sufficient stability, reliability. results indicate that have potential applications

Abstract With the widespread application of electronic communication technology, resulting electromagnetic radiation pollution has been significantly increased. Metal matrix interference (EMI) shielding materials have disadvantages such as high density, easy corrosion, difficult processing and price, etc. Polymer EMI composites possess light weight, corrosion resistance processing. However, current polymer present relatively low electrical conductivity poor performance. This review firstly discusses key concept, loss mechanism test method shielding. Then development status is summarized, research progress with different structures illustrated, especially for their preparation methods evaluation. Finally, corresponding scientific technical problems are proposed, trend also prospected. "Image missing"

With rapid development of 5G communication technologies, electromagnetic interference (EMI) shielding for electronic devices has become an urgent demand in recent years, where the corresponding EMI materials against detrimental radiation plays essential role. Meanwhile, with high flexibility and functional integrity are highly demanded emerging applications. Hitherto, a variety flexible lightweight multifunctionalities have been developed. In this review, we not only introduce materials, but also elaborate mechanisms index "green shielding" performance. addition, construction strategies sophisticated summarized. Finally, propose several possible research directions near future, which could be inspirational to fast-growing next-generation reliable multipurpose protections as offered by materials.

Thermal conduction for electronic equipment has grown in importance light of the burgeoning 5G communication. It is imperatively desired to design highly thermally conductive fillers and polymer composite films with prominent Joule heating characteristics extensive mechanical properties. In this work, "solvothermal & situ growth" method carried out prepare "Fungal tree"-like hetero-structured silver nanowires@boron nitride nanosheet (AgNWs@BNNS) fillers. The AgNWs@BNNS/ANF are obtained by "suction filtration self-assembly hot-pressing". When mass fraction AgNWs@BNNS 50 wt%, film presents optimal thermal conductivity coefficient 9.44 W/(m ⋅ K) excellent tensile strength 136.6 MPa, good temperature-voltage response characteristics, superior electrical stability reliability, which promise a wide application potential devices.
